Hmph. So, looking at tablespace.c, what we're seeing is chmod() returning
EACCES. AFAICT from googling, Microsoft do provide chmod() directly, it's
not some emulation of ours ... but they don't document that an EACCES
failure is even possible, let alone what the triggering conditions are.
Sigh.

Perhaps it'd be useful for investigation purposes to replace the chmod()
with whatever the native Windows equivalent is, and see just which
Microsoft error code it returns.
